Figure 4.2 Hierarchy of cellular functions (see text for discussion).

It is helpful to consider cellular activities in terms of a hierarchy that collectively provides a framework within which the various levels of function can be viewed as an ordered whole. These are the genome, the transcriptome, the metabolome and the fluxome (Figure 4.2).
